and useful Improvements in Cooking-Stoves for Using Wood or Coal; and Ido hereby declare that the following is a full and correct descriptionof the same.

The nature of my invention consists, 1st, in the construction of a setof flues and dam pers belonging thereto between two horizontal platesand placing the same over the fire chamber; 2nd, in the construction ofthe boiler aperture in the lower plate of the two above named; 3rd, inconstructing the draft aperture through the lower plate above named;4th, in the points I admit the fresh air to the fire chamber; 5th, inthe points at the bottom. of the oven; 6th, in constructing the coalcylinder to suit the same draft as that to, the boilers; 7th, thearrangement to put on the pipe at two different places.

- I construct mystove with one or more boiler apertures one pair doubledoors in front; and two' side doors to the large size stove and all theother appendages thereto. belonging. To use all of my improvements, Iconstruct my stove with the even under the fire chamber, but the sameprinciple of draft may be used to the boilought to be about one halfinch less in order that the bottom of the boilers, may have a slopeandyet fit them neatly, and at about twoinches from the front boilerapertures Iplacea set ofcircular partition plates E set verticallybetween plates 0 and D and curving around between the two front boilerapertures so as to :form one side of the circular flues N, around eachkettle in the boiler apertures (the remainder of the flues being formedby the side plates). The flues N around the apertures open into the backflues at the back thereof, said openings being stopped by the slidedampers F and G, thence the flue passes around the back apertures. at Nand out at the spaces J and K into the pipe. In order to admit the flameand heated air into the circular flues N, I make apertures O to each,through the horizontal plate G at the front and sides being at thegreatest distance from the center of the fire chamber that thearrangement will admit of thereby causing the fire to draw from thecenter to each kettle. The back apertures O situated at the sides of thestove opposlte the boiler apertures, Nos. 3 and 4 are formed by takingan oblong notch out of plate C, at those places about 8 inches long and4 or 5 inches wide have damper plates U V to coverv them and are made toopen and shut by means of rods W and X with which they are connected,thereby admitting or cutting off the draft into theflues between theplates C and D, at pleasure, all the damper rods to the rising draftpass out the side of the stove between and over the two side doors. Iadmit the fresh air into the fire chamber by means of one or moreapertures Y and Y at the back part of the fire chamber which areprovided with a hearth (Z Z) (these are shown clearly at Fig. 3 in theback plate of the stove). I admit the flame and heated air to thebottomof the oven through an aperture G D Fig. 4: about 3 inches wide andthirty inches long in the hearth or fire plate, E, F, in the front ofthe fire chamber immediately behind the front or double doors whichaperture is provided with a damper plate G, H, which reaches across thefire chamber, this damper plate Gil-I is hungat the edge I J on a rodwhich damper plate answers two purposes to wit 7 when turned up, itserves to keep the wood and coal from falling down the draft aperture aswell asto cover it up when turned down. In order to clear out the sootand ashes that collect under the oven I make two apertures O P situatedat the bottom of the back end, at each side of the pipe chamber, 5inches long and two inches high, with tight slide doors. In order. todraw off all the steam and smoke arising at the time any thing isbroiling or roasting in front of the double doors I make use of a draftaperture m which is cut through the front plate just above the doubledoors, 2 inches wide and four inches long which passes into the flue atleading to pipe L independent of and between the circular flues; overthis aperture I place a sheet or cast iron cover as represented at Q Rwith a rim turned down which forms a kind of fire place in the hearth ofthe stove and the draft aperture spoken of is the chimney to the same.For burning coal I make use of a cast cylinder S T (see Figs. 4 and 5)constructed for that purpose. It rests on the top plate D by a flange onthe cylinder when let down through the boiler aperture and rests on aflange U V coming in contact with the plate D the lower end passesthrough within about two or three inches of the hearth or fire plate EF. The grate X Y for the bottom of the cylinder is to be loose and restson a flanch in order that it may be replaced. There is a draft aperture(W X Fig. 4) in the side of the cylinder commencing 2 inches below theflange U V and extends down to plate C.

To heat flat irons with coal I make use of a sheet iron pan A B G thatfits into cylinder S T with a draft apertureXZin the side and oppositeto aperture IV X in the cylinder when in place. (The pan in Fig. 5 isshown drawn out of cylinder S T.) This pan is made with a loose grate orbottom B O D (see Fig. 4:) in it resting on flanges near the top. Forusing coal a cast iron grate (C D E Figs. 4 and 5) is placed in the panon which the flat irons are put.

The horizontal slide plate T see Figs. 2 and 4 having been slid over theaperture 0 in plate 0 a draft is formed through the cylinder and causesthe heat and flame to rise into the pan among the irons and out at thedraft aperture X Z in the pan and the draft aperture W X in thecylinder. The pan must have a lid on it when used; for heating flatirons with wood a sheet iron bottom B C D is placed in the pan and thepan put in the aperture in plate D and passes through plate C, the slideplate T on the aperture 0 is then removed.

To heat water when the irons are heating with coal place the boiler Fig.1 in the top of the pan in the lugs or flanch made for that purposeabout two inches from the top. This boiler must be provided with a sheetiron ring G, H, I, which can be slid on or off at pleasure, of such aheight as will allow the boiler (when the pan A B C is not used) to passinto the cylinder just to the top of the draft aperture W X therebypreventing the aperture from being closed by the boiler going in toofar. This ring G H, I must have a flanch turned out at the lower end forthe purpose of closing up the aperture in plate D. (Note.When the pan isused with wood, the aperture in the side should be closed; there may bea lip left on one part of the lid which when turned in the properdirection will close it up and prevent the heat drawing out of the paninto the flues.)

In order to bake griddle cakes or frying things over the boilerapertures with the least possible quantity of wood or coal I make use ofa ring R S W to fit and pass through the boiler aperture with a row ofround or other apertures close to the under side of the top plate D thenslide the damper over the draft aperture 0. The griddle or frying pan isthen placed over the aperture in the ring R- S W and the draft is causedto pass up to the bottom of the griddle or pan to get out the row ofapertures in the ring R S W. The two griddle lids D E F to fit theboiler apertures are to answer two purposes to wit: to close the top ofthe aperture and to be a substitute for a kettle to fill the loweraperture in plate C by means of a flanch that extends down to it inorder that the flue may be formed when there is no kettle in it therebycausing the draft to pass out at the draft apertures made for thatpurpose I have an arrangement by which I can put on the pipe at twodifferent places, thereby giving an opportunity to increase the numberof boiler apertures and not alter the size of the patterns; that is Ican make a three boiler and four boiler stove with one set of patternsand so on from 4 to 5 (as shown in the drawings) increasing to any size.This is effected by having an enlargement E F G at the back of the stovejust at the top and an aperture F G H formed on the enlarged part behindto receive the pipe. To increase the number of boiler holes the pipe istaken off the top and placed on the aperture formed in the enlargement EF G. When a kettle belonging to the other apertures is used on the pipeaperture there must be a sheet iron ring N O P placed on the bottom toprevent it from going through too far and choke the flue beneath it. Theboiler apertures should be numbered by placing a figure at a convenientplace to be seen and a corresponding one at each damper rod belonging tothe same thereby telling with a moments reflection what rod to move todirect the draft to, or from the desired boiler.

forth, by which I admit the flame and heated' air through the lowerhorizontal plate G into the flues N above named at one side or portionof the boiler apertures thereby oblinging the draft first to cross thebottom with the plates C and D, in the manner and of the boilers orkettles and then through the for the purpose above described.
